even 400W psu would be powerful enough. If you are planning another hd 6870 for crossfire 650W is good enough. 750 can surely keep the load withing 80% range which gives better efficiency and less heat generation probably.

Me too! I can't decide on something unless I am absolutely 100.00% certain about it - and it takes me a long time to get there. hehe

Believe it or not, even a quality 650W would be above that efficiency sweet spot.

Don't listen to that, mate Overclocked Athlon II quad can play everything, no visible bottleneck. Only if you are a benchmark nut, which you're not

Plenty for a CFX setup. Simple math:
Overclocked Deneb(X4 955) ~ 140W
Overclocked BartsXT(6870) ~ 180W each
Everything else < 50W

^And that's a full load.

It is way more than enough.

For a system that has one 6870 in it, AMD recommends a PSU that has a peak capacity of 500W. Most 500W peak-rated power supplies can continuously deliver up to about 350w to 400W or so (and AMD is saying that this is enough). The 650W XFX "XXX" Edition has a peak that is somewhere over 750W and is capable of continuously delivering 650W.
